L-Methionine

L-Methionine factory supplier

  1. Nombre en inglés: L-Methionine (pronounced “el-meh-THY-oh-neen”—it’s one of the 9 essential amino acids; your body needs it but can’t make it, so you have to get it from food or supplements!)
  1. Especificación
    • Purity: ≥ 99% (HPLC tested—pharmaceutical/food grade, no additives; the “L-” form is the one your body actually uses)
    • Solubility: Highly water-soluble (mixes easily into drinks, shakes, or supplement powders—no clumps)
    • Moisture: ≤ 0.5% (keeps it dry, so it doesn’t clump or lose potency)
    • Heavy Metals: ≤ 5 ppm (super safe for oral use—meets global amino acid and supplement standards)
    • Stability: 2+ years at room temp (no fridge needed—just keep it in a sealed container away from light)
  1. Apariencia: White to off-white fine crystalline powder with a mild, slightly nutty, neutral aroma—no a yellowish-white solid with chocolate scent! It’s nearly odorless, so it won’t ruin the taste of your drinks or foods.
  1. N.º CAS.: 63-68-3
  1. Plazo de entrega: 3–7 Working Days (we stock both small packets and bulk powder—fast for supplement brands and DIY wellness folks)
  1. Paquete:
    • Small sizes: 100g/500g resealable foil bags (moisture-proof for home use) or 30-count capsules (easy to take on the go)
    • Bulk: 25kg food-grade drums (lined with plastic—27 drums per tray; includes desiccants to keep it dry)
  1. Mercado principal: Global—North America (supplement brands), Europe (sports nutrition), Asia (functional foods and infant formula). Big with gym-goers, vegans (since it’s mostly in animal products), and people focused on liver health.
  1. Applications & Main Benefits
    • Suplementos dietéticos
      • Amino Acid Stacks: 500–1000mg per serving (paired with other amino acids like lysine—boosts muscle repair for gym-goers)
      • Vegan/Vegetarian Supplements: Fills the gap (since L-Methionine is scarce in plant foods—keeps veg diets balanced)
      • Liver Support Capsules: Mixed with milk thistle (helps the liver break down toxins—great for people with occasional alcohol intake)
    • Alimentos y bebidas funcionales
      • Protein Shakes: Added to plant-based (soy, pea) proteins (boosts amino acid completeness—makes shakes more nourishing)
      • Fortified Cereals: Sprinkled on breakfast cereals (adds an essential amino acid—easy morning nutrition)
      • Infant Formula: Included in baby formula (critical for growth and brain development—mimics breast milk’s amino acid profile)
    • Nutrición deportiva
      • Pre-Workout Powders: Small doses (250–500mg) mixed in (supports energy production—helps you push harder during workouts)
      • Post-Workout Recovery Drinks: Paired with whey protein (speeds up muscle repair—cuts down on soreness)
    • Bienestar de las mascotas
      • Dog/Cat Supplements: Tiny doses (50–100mg) in pet vitamins (supports liver health in senior pets—eases age-related detox issues)
      • Pet Food: Fortified into premium kibble (ensures pets get all essential amino acids—keeps coats shiny and muscles strong)

Key Benefits (Why It’s Essential!)

  • Muscle Health: Helps build and repair muscle tissue—critical for gym-goers, older adults (fights muscle loss), and anyone active
  • Liver Detox: Supports the liver’s ability to break down toxins (converts harmful substances into ones your body can flush out)
  • Amino Acid Balance: Vegans/vegetarians often lack it—supplements keep their amino acid intake complete (no nutrient gaps)
  • Brain & Nerve Function: Helps make neurotransmitters (brain chemicals) and myelin (the protective layer around nerves)—keeps your brain sharp and nerves healthy
  • Skin & Hair: Aids in making collagen and keratin (proteins that keep skin elastic and hair strong—fights dryness and breakage)

Quick Tip

Take L-Methionine with food (especially carbs!)—it helps your body absorb it better. Vegans can pair it with legumes (like beans or lentils) to make their meals’ amino acids more complete. And since it’s water-soluble, your body flushes out what it doesn’t need—no need to worry about “overdosing” on standard doses!
